CSR Components

CSR Components

The three major components of CSR are as follows.

•

postgreSQL Database

•

CSR application

•

CSR GUI

The CSR GUI and the CSR application are not directly connected. They are both connected to the 
database. 

Figure1-1

 illustrates these components.

CSR Basics

This section describes the basic operation of CSR.

After CSR is started, it registers with the gatekeeper connected to a network. Any one or a combination 
of the following registration messages are used:

•

ARQ

•

LRQ

•

DRQ

•

BRQ

•

URQ

•

RAI

•

LCF

•

LRJ

•

IRR

The gatekeeper responds with any of the following messages:

•

ANI

•

DNIS

•

Source carrier

•

Destination carrier
